Description:TriBotz is three robots in one package! It uses sensors to avoid objects, follow a line and respond to sound. The TriBotz will react to sound impulses and objects in the way. It will reverse away from a sound or obstruction, and then move forward. Make a path with a black felt tip marker or black tape and watch how infrared sensors allow the TriBotz to make corrections. No soldering required. Requires two (2) AA batteries (not included). Ages 8 and Up.
